Using Oxygen Molecules for Odor Removal

  1. Ozone 101: Using Oxygen Molecules for Odor Removal
    Restoration & Remediation (01/07/16) David Hart

Ozone, which can be manufactured through corona discharge generators or ultraviolet light generators, can be used to destroy odors because it transfers the extra oxygen atom to the odor molecule and changes its composition through oxidation. Following oxidation, the odor-causing molecule is changed, and its odor changes as a result. This differs from using deodorizers because deodorizers render the smell inert for a certain period of time. Treating odors with oxidation alters the odor’s molecular structure, transforming the odor into a different and harmless molecule. During the oxidation process, technicians need to ensure the premises are evacuated, pets removed, and houseplants are relocated. It is a good idea to post “Do Not Enter-Ozone Area” (or similar message) signs on all entrances of a space as well. After the treatment is completed, the space should be circulated with fresh air. Ozone has a relatively short half-life of approximately 30 minutes, and technicians need to use proper protections when engaging in treatment. Moreover, the only residue resulting from the generation of ozone is oxygen, making ozone a safe and effective tool when used properly
